CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Australian Plant Breeder'sRights application number 2015/146, filed on Jun. 15 2015, which isherein incorporated by reference.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Eremophila glabra.

Variety denomination: The inventive variety of Eremophila glabradisclosed herein has been given the variety denomination ‘EREM1’.

BACKGROUND OF THE INVENTION

Parentage: ‘EREM1’ is a whole plant mutation of a low-growing Eremophilaglabra plant (unnamed and unpatented) which was discovered in Septemberof 2013 by the inventor at his commercial nursery in Clarendon, NewSouth Wales, Australia. In 2012, the parent plant was asexuallyreproduced by way of stem cuttings. Of the resulting plants, one plantin particular exhibited improved plant vigor and a prostrate growthhabit. The new plant was isolated and grown to a mature size to confirmthe distinctness and stability of the characteristics initiallyobserved. After further evaluation and confirmation of the desirabletraits, the claimed plant was selected for commercialization and giventhe breeder denomination, ‘EREM1’.

Asexual Reproduction: ‘EREM1’ was first asexually reproduced by way ofsoftwood stem cuttings in 2013 at the inventor's nursery in Clarendon,New South Wales, Australia. It was found to grow uniform and reproducein a stable manner and 5 successive cycles of vegetative propagationhave proven to be true to type also.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed andrepresent the distinguishing characteristics of the new Eremophilacultivar ‘EREM1’. These traits, in combination, distinguish ‘EREM1’ as anew and distinct cultivar.

1. ‘EREM1’ exhibits a short plant height and prostrate growth habit; and

2. ‘EREM1’ exhibits a very vigorous rate of growth; and

3. ‘EREM1’ exhibits foliage with a silver appearance; and

4. ‘EREM1’ exhibits obovate foliage.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinctvariety of a Eremophila ornamental plant known as ‘EREM1’. Plantobservations were made on plants grown in Clarendon, New South Wales,Australia. Unless indicated otherwise, the descriptions disclosed hereinare based upon observations made from 1 year old mature ‘EREM1’ plantsgrown outdoors in full sun. Plants were fertilized with a slow releasegranular fertilizer product and were periodically watered with overheadirrigation, as needed. No pest and disease measures were taken.Observation data was recorded in the June of 2016.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, younger plants. ‘EREM1’ has notbeen observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety mayvary with variations in the environment such as season, temperature,light intensity, day length, cultural conditions and the like. Colornotations are based on The Royal Horticultural Society Colour Chart, TheRoyal Horticultural Society, London, 2001 edition except where commonterms of color are used.

Plants of    ‘EREM1’ are very vigorous and exhibit a very short plant height,    whereas the parent plant exhibits a medium to tall plant height and    are less vigorous.-   Comparisons with the closest known variety: ‘EREM1’ may be    distinguished from its closest know commercial comparator,    Eremophila glabra ‘Kalbarri Carpet’ (unpatented) by the following    combination of characteristics: 1. EREM1’ grows to approximately 200    to 250 mm tall, whereas ‘Kalbarri Carpet’ grows to approximately 150    mm tall. 2. The leaves of ‘EREM1’ are of short to medium length with    an obovate shape, whereas leaves of ‘Kalbarri Carpet’ are of medium    to long length and lanceolate. 3. The stem internodes of ‘EREM1’ are    shorter than those of ‘Kalbarri Carpet.

That which is claimed is:
 1. A new and distinct variety of Eremophilaglabra plant named ‘EREM1’, substantially as described and illustratedherein.
